2 Claims. (Cl. 206-46) The herein disclosed invention relates to cartons for packaging irregular articles having a body, a coil and a tube connected to the end of the coil.

An object of the invention resides in providing a carton in which the various parts of the articles are in different compartments and are separated from one another and protected from injury.

Another object of the invention resides in providing a carton constructed of a single blank of cardboard or corrugated board.

An object of the invention resides in providing the carton with a bottom having lateral edges and from one of which issues an upwardly extending shelf support of a height less than the height of the carton and from the upper edge of which issues a shelf overlying and spaced from the bottom.

Another object of the invention resides in providing a partition extending upwardly from the inner lateral edge of the shelf and disposed inwardly of the other lateral edge of the bottom.

An object of the invention resides in providing the shelf with an opening to receive the body of the article and a leg depending downwardly from said partition and resting on the bottom.

A feature of the invention resides in providing a wall structure issuing from the other lateral edge of the bottom and enclosing the first named parts of the carton.

Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/ or described.

In the drawings:

Fig. l is a perspective view of the carton partially erected.

Fig. 2 is an end view of the erected carton with the flaps open.

Fig. 3 is a developed view of the blank from which the carton is constructed.

The carton of the instant invention is particularly adapted to package an article 50 such as shown in Figs. 1 and 2. This article is a thermostatic control and comprises a body 51 in the form of a rectangular case which has a coil 52 of flexible tubing 53 connected at one end to the mechanism within said body. The other end of the tubing 53 has connected to it a tube 54 of larger diameter which, for the article illustrated, constitutes a thermostat. Such articles are particularly difficult to package and the instant invention provides a carton in which the various parts of the article are properly spaced, supported and protected.

The carton shown in the drawings is indicated by the reference numeral 10. This carton is constructed from a blank 11 of cardboard or corrugated board which is shown in detail in Fig. 3. This blank is elongated in form and is provided with transverse scores 12, 13, 14, 15, 16, 17, 18 and 19 which form in the blank a flap 21, a partition 22, a shelf 23, a shelf support 24, a bottom 25, a side wall 26, a top wall 27, a side wall 28 and a false which lie substantially in alignment with the edges 31 and 32 and which form flaps 35 and 36 which extend outwardly beyond said scores. The false blank 11 is also formed with scores 37 and 38 which lie substantially 'in continuation of the scores .33 and 34 and with scores 41 and 42 which are parallel to the scores '37 and 38 and which lie outwardly therefrom. By means of this construction, flaps 43 and 44 are formed at the ends of the false bottom 29 and tongues 45 and 46 at the ends of said flaps. The flaps 43 and 35 and the flaps 44 and 36 are separated from each other by means of kcrfs 47 and 48 which lie substantially in continuation of the score 19 and which commence at the scores 33 and '34 and extend through the outer edges of the blank.

The shelf 23 is constructed of a width less than the width of the top wall 27 and bottom 25 of the carton. When the parts are folded up, as shown in Fig. 2, a compartment 64 is formed between said partition and the ad- 'join'ing side wall 26 of the carton;

The shelf 23 is formed with a cut-out 55 providing an opening 56 therein adapted to receive the body 51 of the article 50. Formed from the material of the blank at the cut-out is a projection 57 which normally extends into the opening 56. The score 13 does not extend across the projection 57 so that said projection becomes a part of the partition 22 and when said partition is: folded along the score 13 follows the partition and lies outwardly of the opening 56. The projection 57 is adapted to engage the bottom 25 and when the carton is erected serves as a leg for supporting shelf 23.

' The flap 21 is formed shorter than the partition 22 and the lateral edges 58 and 59 lie inwardly from the edges 31 and 32 thereof. Formed in the said partition, adjacent, the score 12 and at the locality of the edges 58 and 59 of the flap 21, are notches 61 and 62 which serve a purpose to be presently described.

The method of using the invention is as follows: The carton is first folded along the scores 14 and 15 to cause the shelf support 24 to extend upwardly from the bottom 25 and the shelf 23 to lie spaced from and parallel to said bottom. The blank is then folded along the score 13 to cause the. partition 22 to extend upwardly from said shelf. The leg 57 being integral with the partition 22 follows with it when the same is bent along the score 13 and projects downwardly therefrom as shown in Fig. 1 where the same may rest upon bottom 25. With the parts so arranged, the body 51 of article 50 is inserted into the opening 56 and projects through the same and rests upon the bottom 25. Coil 52 is caused to rest upon the shelf 23 as shown in Fig. 2. The end of the tubing 53, indicated by the reference numeral 63, is directed through the notch 61 causing the tube 54 to extend along the partition 22 and to be disposed in compartment 64 as shown in Fig. 2. Flap 21 is next folded along the score 12 and caused to overlie the body 51. The remaining parts of the carton may now be folded along the scores 16, 17, 18 and 19 and the various portions of the carton wrapped about the previously mentioned portion of the carton. When completed, the side wall 26 extends upwardly from the bottom 25, the top wall 27 overlies the flap 21, the side wall 28 overlies the shelf support 24 and the false bottom 29 overlies the bottom 25. The flaps 35 and 36 may next be folded in and the flaps 43 and 44 thereafter folded in and the tongues 45 and 46 inserted into the carton between the top wall 27 and flap 21 to hold the various parts of the carton in closing position. When so assembled the parts of the carton to the left of score line 16, as viewed in Fig. 3, constitutes a wall structure enclosing the portions of the carton to the right of said score line and the article 50.

The advantages of the invention are apparent. All of the parts of the article are separated from one another to prevent abrasion therebetween and the parts are rigidly supported and cushioned and held in proper relation to one another to prevent breakage or injury during transportation. The carton is constructed from a single blank and without appreciable waste of material. The carton is easily erected and the article placed therein. The carton may be repeatedly opened and closed and when closed protects the article from injury or breakage.

Changes in the specific form of the invention, as herein described, may be made within the scope of what is claimed without departing from the spirit of the invention.

Having described the invention, what is claimed as new and desired to be protected by Letters Patent is:
